ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and drivetrain (transmission and
axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws
contributes to a good break-in. Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For the recommended viscosity
and quality grades, refer to “Maintaining Your Vehicle.”
NOTE:
A new engine may consume some oil during its first few thousand miles (kilometers)
of operation. This should be considered a normal part of the break-in and not
interpreted as an indication of an engine problem or malfunction.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
• The 3.0 turbocharged diesel engine does not require a break-in period due to itsconstruction. Normal operation is allowed, providing the following recommenda-
tions are followed:• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
• The engine oil installed in the engine at the factory is a high-quality energy conserving type lubricant. Oil changes should be consistent with anticipated
climate conditions under which vehicle operations will occur. The recommended
viscosity and quality grades are shown under “FLUIDS AND CAPACITIES”, under
“MAINTAINING YOUR VEHICLE” in this User Guide. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.
DIESEL ENGINE STARTING PROCEDURES
Normal Starting Procedure
1. Apply the parking brake.
2. Ensure the shift lever is in the PARK position.
3. Press and hold the brake pedal while pressing the ENGINE START/STOP button
once.
4. The system will take over and attempt to start the vehicle. If the vehicle fails to start, the starter will disengage automatically after 30 seconds.
5. If you wish to stop the cranking of the engine prior to the engine starting, press the button again.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.

- Transmission Temperature Warning Light
This light indicates that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle, with the transmission in NEUTRAL, until the light turns
off. Once the light turns off, you may continue to drive normally.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated
will eventually cause severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the Transmission Temperature Warning
Light is illuminated you could cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
OIL CHANGE EVIC INDICATOR
Message
If an “oil change” message (shown as “Change Oil Soon” and “Oil Change Needed”)
appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
1. Turn the ignition switch to the ON/RUN position (do not start engine).
2. Fully depress the accelerator pedal three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
- Low Coolant Level Indicator Light
This light indicates low coolant level. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
WHAT TO DO IN EMERGENCIES
174
CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic AdditiveTechnology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
E-85 Flexible Fuel — 3.6L Engine Only
CAUTION!
Only vehicles with the E-85 fuel filler door label or a yellow gas cap can operate on
E-85.
Refer to your Owner's Manual on the DVD for further details.
MAINTENANCE SCHEDULE — GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).

Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by referring to the steps described
under “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
